AI Explanation

The correct answer is A) 27 amps. To calculate the total current in the circuit, we can use the formula for capacitive reactance (Xc = 1 / (2πfC)), where f is the frequency and C is the capacitance. For the given values of C1 = 100 microfarads, C2 = 200 microfarads, and the power supply of 240 volts at 60 Hz, the total capacitive reactance (Xc1 + Xc2) is approximately 21.2 ohms. Using Ohm's law (I = V/R), the total current in the circuit is calculated to be 27 amps. The other answer choices are incorrect because they do not accurately reflect the total current based on the provided circuit parameters.
